Promotion effect of FeOx addition on the catalytic activity of supported Cu catalysts for the water-gas shift reaction
Among the supported Cu-FeOx catalysts, Al2O3-supported Cu-FeOx catalyst exhibited the highest activity for WGS reaction. The enhancement of the catalytic activity by adding FeOx to Cu/Al2O3 could be interpreted by the two possibilities; one is the formation of highly dispersed Cu-0 and the other is the participation of reduced FeOx in WGS reaction in the presence of Cu-0.
